i am having following error in twrp. due to this i cannot take backup. any way to fix this.
just now i wiped data completely, still it didn't fixed the error.
please help me to resolve this.
What version of TWRP are you using and exactly what were you trying to do before you got the error?
That looks like some encryption stuff to me.
This error displays as soon as I go to TWRP and i was unable to do nandroid back up.
I went to wipe advance wipe and selected data, instead of wipe, there was a button above the swipe option, i clicked that and repaired partition, and i think it fixed the issue.

Hi, today i wanted to do a factory reset and clean install my phone
im using TWRP 2.3.3.3
after factory reset in the wipe menu, at the end i see a line E:/error opening '/data/lost+found'
basically i know what does lost+found folder does in linux, but i forgot whether i have seen such error line before when i do factory resets.
in the file manager of TWRP i then see /media and /lost+found in the /data partition. when pressing into /lost+found, TWRP cannot open it
after this, wiping /system will also give me the same message at the end even it is "Done", as well as cache and dalvik, etc
then i go on flash rom, gapps, kernel, after 1 or 2 boots i go back to recovery and wipe cache, there are no such line anymore
however there is now TWO /lost+found folder in my /data partition
is this a normal behaviour? i didnt pay attention but are there 2 lost+found folders in /data partition for everyone else too?
i have backed up my sdcard and is ready for a /data wipe, any advice is appreciated. thanks in advance!
update: well really hasnt seen it anywhere tried very hard searching on google
maybe just **** happens sometime as i rushed updating the su binary together with restoring android ID in titanium backup altogether without carefully rebooting etc.
factory reset, formating every partition for N times didnt help. returned to completely stock (unlocked bootloader ofcourse), flash twrp 2.3.3.3 clean and no more that line anymore after factory reset. hell gonna start my sdcard restore now...

I was researching google for this same exact error message, when I came across your thread. I doubt you are still having this issue, but I wanted to reply with the solution in case anyone else comes across this post. I was able to solve this error message by installing a new ROM. It doesn't matter which one you install, any will do. Then open your file manager of choice, of course one which can go up to root level. Browse to /data, and then you should notice that you do not have a lost+found folder. However, you should see a lost+found file, all the way at the bottom. I renamed this file to lost+foundOLD, and then created a new folder called lost+found. Next, reboot into recovery and once again wipe both caches, system and factory reset. You should no longer get the lost+found error. Make sure to fix permissions as well to make sure.
just had this issue and was solved by dropping back to twrp 2.4.x.x and doing data format.

No his error and mine are different. We have two lost+found dir and no file. If i delete them and make new lost+found folder. It automatically makes 2.
I am having this same problem. I just did a restore to my last backup, but it in TWRP it says mentions the error over and over again. I looked in /data and I found about 10 files called lost+found, but I do not have any folders. Any suggestions?
Full Format data worked for me

I just encountered this problem after updating a CM nightly and it bricked my phone. Restoring from a nandroid backup would ultimately fail and I was getting all kinds of weird problems (stuck in boot loop, graphics appearing garbled, etc). After looking closer at the logs during restore, I noticed E:/error opening '/data/lost+found' appearing several times, an then it would indicate 'done' and restart but would end up with the same problems.
Even after doing a factory reset, I had no luck in restoring my phone. So I did a factory reset again and installed a CM stable release thinking maybe my ROM / backup was messed up but noticed the same E:/error opening '/data/lost+found' message. However, this time around I managed to get booted far enough where I could connect via USB and backup files from my internal memory to my computer.
At this point I booted into recovery (TWRP 2.5.0.0) and did a full wipe including internal SD using the Format Data option, whereupon I was able to install the CM stable release without issue - no more lost+found error! I then upgraded to the nightly version of my backup and restored with success. Long and stressful night...

All you simply have to do when this happens, is format data ( the one where you type yes ). After this, everything SHOULD be back to normal, for the most part.

Worked perfect for me. Very easy to miss that simple "Format Data" button in TWRP. Simply type 'yes' and problem solved.
I think I got this error when I flashed SlimKAT 4.4 over on my P880 and I had the USB cable plugged in and the partitions mounted (as I had just transferred the install.zip to my phone)

Can i get some help please. I cant format data via TWRP, it says "E: unable to wipe data, unknow fle system, auto, unable to format to remove encryption". I did not put any encryption. What to do?
Don't know how I did this but I'm having an error in Recovery...comes up as
E:error opening '/data/data/com/instagram.andro
E:error: I/O error
This error is preventing me from restoring backups (they fail)..
Its also kept me from clean installing a new ROM (Rom will boot but I get the process stopped pop-up message repeatedly)...
I've done a total wipe of everything except for internal storage.. but the results are the same. Any help or insight would be appreciated. ***Error also occurs after wipe*** But wipe is "successful"
TIA
Got this issue sorted last night. Apparently, TWRP does a poor job of wiping so I had to switch to Philz recovery and wipe in order to remove that pesky error. From there I was able to perform a clean install of a new ROM, use Freegee to install TWRP and finally load one of my backups.
New issue...
Tap to wake no longer works ...
Any help for the new problem?
Hi,
I have G935F, installed TWRP 3.0.0.0 and rooted, WITHOUT wiping. System boots correctly, but I cannot do factory reset or wipe with TWRP, because I got some messages like "Cannot mount Data" and "Failed crypto loader". I understand that it has to do with encryption. Can someone please enlight me, and give me tips about the issue?
Thank you

You have to download dm-verity and force encryption disabler from here , put it to SD card, reboot into TWRP, FORMAT DATA (not wipe) and flash that file (dm-verity and force encryption disabler). All your data will be erased.
No way to unencrypt without loosing you data for the moment(
"All your data will be erased" means that after boot I'll find a clean system installation (as factory reset)?
I hope not to be posing stupid questions, I'm completely new to this world
Thank you very much
Yes just as a factory reset

No, you cannot perform a backup, because your data is encrypted by default and the only way to disable it is to format your data.
I have a unique problem. I have a HTC Desire 612 from Verizon and I decided to revive it to playe PoGo. But it was stuck in a boot loop and I couldn't get any custom ROM.
Finally a gentle soul here gave me the stock rom and I flashed it vide TWRP and played PoGo for weeks. Then yesterday the phone bro led and when it came up it was stuck in a boot loop.
So I decided to flash the stock ROM again. But before that I tried to factory reset. I could go to TWRP, select wipe data, enter yes and the wiping was successful, then clear dalvic and cache and system beforehand finally I flashed the stock ROM.
Surprise surprise is NOTHING happens. The phone boots without the apps telling me they are installing. Then I get back the exact same data in my phone including my selected wallpaper and apps. Before I can do anything the phone restarts.
Point is wiping and restoring the stock ROM does NOTHING to the phone yet the processes are successful. Can somebody help?

It really is about TWRP failing to wipe
I installed TWRP on my device. It worked nicely and I booted into twrp recovery. I thought of doing a factory reset. So, I selected the format option on TWRP. It showed something like "Formatting Data using make_extfs". I left it there. My brother came and pulled out the battery from the mobile. I booted up the phone thinking the process was over. I was stuck in a bootloop. I then booted into twrp again. I tried to wipe cache, but a error message came up showing something like "Failed to mount /data". I tried recovery option on TWRP. There it is showing, 0 MB internal storage. I think the storage got corrupted. Any solutions to this?
Try wiping your all partitions. All at once
So I flashed the latest version of TWRP on my s7 edge SM-G935F
And I got the error "failed to mount data" I formatted my phone and I didn't see the error again, I rebooted my phone and everything was working fine then when I wanted to root my phone with Magisk, i went back to TWRP recovery and I got the error again, so I formatted my phone again and rooted it, then I rebooted my phone and I said that the data is corrupted that I should reset my phone to factory reset, I went back to TWRP recovery and still get the same error.
It's like the TWRP recovery is not stable and it also reset immediately you leave so that when you come back you must format your data or factory reset it before you can use the recovery.
Can Anyone help fix this problem, I don't want to wipe/factory reset my phone every time I go to recovery. What if I make a mistake and go to recovery? That means I must wipe/factory reset my phone before using.
Please help!

If it's telling you "failed to mount /data", go to wipe > format data and type yes. Factory reset, do your things and then reboot back and install what you want, you shouldn't get the error anymore.
But later if I want to flash another thing like a mod, I have to wipe data again

Nono. Wipe data once, factory reset in twrp, and you don't need to wipe data again after that. Only wipe it once after you format data.
